A beloved staple across Southern kitchens, chicken spaghetti gets a kicked-up twist with spicy peppers, seasoned chicken, and a luscious cheese sauce baked until golden and gooey.

Ingredients Overview

Every layer of this casserole contributes to its crave-worthy flavor and creamy texture. Here’s what makes it special:

Chicken

Shredded, cooked chicken is the heart of this casserole. Use:

• Rotisserie chicken for convenience
• Boiled and shredded chicken breasts or thighs for homemade
• Leftover roasted chicken also works beautifully

Spaghetti

Spaghetti noodles are traditional, though any long pasta can work.

• Tip: Break noodles in half before boiling for easier scooping
• Cook to al dente, as they will finish in the oven

Spicy Kick

This is where the Southern flair shines. Spice it up with:

• Diced green chiles (mild or hot)
• Jalapeños or serrano peppers, minced
• Cayenne pepper or red pepper flakes
• Hot sauce, added to taste

Cheese

A bold, melty cheese blend makes this dish irresistibly creamy.

• Cheddar cheese – for sharpness
• Monterey Jack or Pepper Jack – for extra melt and a little heat
• Cream cheese – adds richness and smooth texture
• Velveeta (optional) – for a traditional, ultra-creamy finish

Creamy Base

To create that signature casserole sauce:

• Cream of chicken or mushroom soup (use homemade or canned)
• Chicken broth – for loosening the sauce
• Sour cream or heavy cream – adds tang and silkiness

Aromatics & Veggies

• Onions & garlic – sautéed until soft and fragrant
• Bell peppers – red or green for color and crunch
• Optional: Add mushrooms or celery for depth

Toppings

• Extra cheese on top
• Crushed buttery crackers or fried onions (optional) for texture
• Fresh parsley – for brightness after baking

Step-by-Step Instructions

1. Cook the Pasta

• Boil a large pot of salted water.
• Cook 12 oz spaghetti until al dente (about 1–2 minutes less than package suggests).
• Drain and set aside.

2. Sauté Aromatics

In a large skillet over medium heat:

• Add 2 tablespoons butter or oil.
• Sauté 1 diced onion and 1 diced bell pepper until soft (5–7 minutes).
• Add 2–3 cloves minced garlic and cook for 1 minute more.

Optional: Add diced jalapeños or chiles at this stage for infused heat.

3. Make the Creamy Sauce

To the skillet, stir in:

• 1 (10.5 oz) can cream of chicken soup
• ½ cup sour cream or heavy cream
• 1 cup chicken broth
• 4 oz cream cheese, softened
• 2 cups shredded cheddar or Pepper Jack
• 1 (4 oz) can diced green chiles
• ½ tsp cayenne pepper or hot sauce to taste
• Salt and black pepper

Stir over low heat until smooth and combined.

4. Combine Everything

In a large bowl or casserole dish:

• Mix cooked spaghetti, 3 cups shredded cooked chicken, and the creamy sauce until fully coated.

Tip: Use tongs or two large spoons to mix well without breaking the pasta.

5. Transfer to Baking Dish

• Spread the mixture evenly in a greased 9×13” casserole dish.
• Top with an extra 1–1½ cups shredded cheese.

Optional: Sprinkle crushed Ritz crackers, fried onions, or panko on top for added crunch.

6. Bake

• Preheat oven to 375°F (190°C).
• Bake uncovered for 25–30 minutes until hot and bubbling.
• Broil for 1–2 minutes at the end to brown the top slightly, if desired.

Let rest for 5 minutes before serving.

Tips, Variations & Substitutions

• Make it extra spicy: Use pepper jack cheese, add more jalapeños, or stir in a splash of your favorite hot sauce.
• Mild version: Stick with diced green chiles and reduce or skip cayenne and hot sauce.
• Vegetarian option: Use cream of mushroom soup and skip the chicken — add sautéed mushrooms or black beans instead.
• Low-carb: Swap spaghetti for zucchini noodles or cooked spaghetti squash.
• Make ahead: Assemble the casserole, cover, and refrigerate up to 24 hours before baking.

Freezing:
Cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge and bake until heated through.
